This wouldn't work. It looks like a bad fake. The right method is doing a raytracing for each star in the galaxy's 3D dust map. For stars that a inside the nebula, a separate raytracing in its 3D dust map is required. Or, instead of ray-tracing, a cunning multi-pass render method, that I plan to experiment with.

It is not easy to move catalog star rendering into this order, because stages 1, 3, 4, 5 are integrated in the galaxy's class render method. Catalog stars is a separate entity in the SE. Some trick must be used to make them embedded into galaxy render pipeline. For example, only galaxy named "Milky Way" or have some key in the script would have catalog stars render in it. But then some problems will be with extragalactic catalog stars, like S Doradus in the LMC - it will be incorrectly faded by LMC's dust sprites.

I'm creating systems for my RPG, and I notice I can make it faster if I generate procedurally new systems with SE, export them and tweak them a bit. But there's some problems with it : when the system is exported, there an average of 400 asteroids/comets on the file that causes an epic slowness when I load them.

I think an option to export systems without asteroids and comets should be great.

After you export the system, just delete all the asteroids and comets from the catalog before putting it back into SE as a catalog system. The asteroids and comets around a star or barycenter are grouped together so they are easy to find and delete.

Anyway, I should note: as long as SE is a scientifically accurate Universe simulator, then one day it will implement ALL space objects and phenomenon that are known to modern astronomy. So you may not bother yourself with questions like "will SE one day have meteor rain implemented". I guarantee that it WILL.

SpaceEngineer, What would the outcome be if, instead of releasing a huge update with over half a dozen new features once a year, you released smaller, 0.97.1 scale updates once a month or every other month, with one new feature and any bug fixes, like Pioneer Space Sim did?
